L-BCX021 6.35 mm Dia. Double-Convex Lens; EFL=19mm Uncoated

The L-BCX021 is a spherical lens with a base shape of circular, sourced from the reputable vendor, Ross Optical. This lens is a double-convex type, characterized by its convex-convex geometry, making it an ideal choice for a wide range of optical applications.

The lens has a diameter of 6.35 mm, ensuring a compact design that fits well in various setups. The edge thickness is 3 mm, while the center thickness measures 3.53 mm, providing a robust structure that can withstand typical handling and usage. The effective focal length (EFL) of this lens is 19 mm, making it suitable for applications requiring moderate magnification and focus.

The L-BCX021 is made of n-bk7 Schott material, a popular choice for its high refractive index and low dispersion, ensuring excellent image quality and color correction. The lens is designed to work with a wavelength of 587.6 nm, which is within the visible light spectrum.

Notably, this lens is uncoated, meaning it does not have any additional layers to enhance light transmission or protect the surface from environmental factors. While this may limit its performance in high-intensity or harsh environments, it can be an advantage in applications where cost or simplicity is a priority.
